What is the doctrine of election in Christianity?

Election is a critical aspect of Reformed theology, where it is understood that God, in His sovereign grace, has chosen a specific people for Himself based on His purpose and will. This doctrine is evident in passages such as Ephesians 1:4-5, which states that believers are chosen in Christ before the foundation of the world for adoption as sons. This highlights God’s initiative in salvation, emphasizing that it is not based on human merit but solely on His grace. Understanding election gives believers assurance of their salvation as they recognize its origin in God's eternal decree.
